When Moe's Tavern is shut down by the health department, Homer refinances the house to save the bar. Infuriated by this, Marge decides to protect her investment and takes an active, hands-on role as Moe's partner. Marge gives the bar a facelift and boosts the clientele, while Homer has to stay home and play Mr. Mom. Meanwhile, Moe begins to develop deep feelings for his new partner.

After sneaking out of the house to attend a 50 Cent concert and getting nabbed by Marge and Homer, Bart fakes his own kidnapping, hiding out in Kirk Van Houten's bachelor pad, to prevent being grounded. It is up to Springfield's finest - bumbling Police Chief Clancy Wiggum - to save him. Inspired by an apparition of Barney Fife, Wiggum cracks the case, rescues Bart and is promoted to Police Commissioner, while wrongly-imprisoned Kirk becomes a lady's man among the felon-loving singles of Springfield.
